Concerns have been raised for decades about whether global food production can keep up, and global waste is set to triple by 2100. The rate of species extinction is up to 10,000 times higher than the natural, historical rate. Half of species in critical risk of extinction by 2100 More than one in five species on Earth now faces extinction, and that will rise to 50% by the end of the century unless urgent action is taken. 28,000 2020-09-05 · The current rate of species extinction is conservatively estimated at 100 to 1,000 times greater than the background rate.
